1 Overview
1.1 Product Overview
The MB86391 (MPEG2 1chip Audio/Video Encoder) is an LSI that accomplishes all of video encoding, audio
encoding, and video and audio encode stream data multiplexing with a single chip rather than several LSIs as
in the past. This LSI enables you to minimize the size, cost and power consumption of MPEG2 application
systems, such as digital video recorders.
An easy control command interface is achieved by firmware dedicated to the internal controller.
